As shown in FIGS. 1 to 3 , the present embodiment provides a lift desk. The lift desk includes a support base 1, a first desk board 2, a second desk board 3 and an adjustment support assembly 4, where the first desk board 2 is connected to the support base 1 by a lift mechanism 5, and the second desk board 3 is connected to the first desk board 2 and positioned between the support base 1 and the first desk board 2. The adjustment support assembly 4 includes a support block 42. The second desk board 3 is provided with a groove 31 at a side of the second desk board 3 facing towards the first desk board 2. The support block 42 is slidably disposed in the groove 31 and configured to cooperate with the first desk board 2 and the second desk board 3 to support a supported object 100.

It is to be noted that in the present embodiment, the supported object 100 refers to a laptop. Of course, in other embodiments, the supported object 100 may be another electronic device, which is not limited thereto.

In the present embodiment, the desk boards of the lift desk can be lifted and lowered to provide a support structure at different heights. The two desk boards can hold more items. The two desk boards are arranged at different layers so that the two desk boards have different heights to meet the placement requirements of different items and facilitate the simultaneous use of the two desk boards. The second desk board 3 is provided with the groove 31 at the side of the second desk board 3 facing towards the first desk board 2, and the support block 42 is slidably disposed in the groove 31, supports the supported object 100 in cooperation with the second desk board 3 and can support supported objects 100 at different positions in cooperation with the groove 31.

Optionally, round corners are provided at two ends of the groove 31. This arrangement facilitates machining the structure of the groove 31 by a milling process.

In an actual production process, the second desk board 3 is made of wood with poor wear resistance. In order to prevent the groove 31 from being worn, in the present embodiment, optionally, the adjustment support assembly 4 further includes a slide rail 41 embedded in the groove 31. The slide rail 41 is provided with a slide groove 411. The support block 42 is slidably disposed in the slide groove 411. The slide rail 41 is made of plastics or other soft materials. Such an arrangement can prevent the groove 31 of the second desk board 3 from being worn and improve the durability of the second desk board 3.

In the present embodiment, optionally, a groove wall of the slide groove 411 is provided with a limiting ridge 412. The limiting ridge 412 extends in the same direction as the slide groove 411 and projects towards the inside of the slide groove 411. A notch 421 is provided on a side of the support block 42. The notch 421 is slidably sleeved on the limiting ridge 412. With such an arrangement, the support block 42 cannot be pulled out in an opening direction of the notch 421 during a slide, thereby preventing the support block 42 from being lost and improving the reliability of the lift desk.

Further, an end of the support block 42 is in contact with the slide rail 41, and a round corner is provided at a side of the end facing away from the notch 421, where a centerline of the round corner is consistent with the direction in which the slide groove 411 extends. When used, the support block 42 is inclined by a certain angle to allow the notch 421 to be fitted with the limiting ridge 412, and then the support block 42 is inclined in a reverse direction so that the support block 42 can be placed in the slide groove 411. In an embodiment, the support block 42 is inclined by 45 degrees to allow the notch 421 to be fitted with the limiting ridge 412, then the support block 42 is reversely rotated around the limiting ridge 412 by 45 degrees so that the support block 42 can be placed in the slide groove 411. Such an arrangement facilitates the mounting of the support block 42 and can prevent the support block 42 from being pulled out in the opening direction of the notch 421.

In the present embodiment, optionally, the number of the support block 42 is at least two. Specifically, two support blocks 42 are provided. This arrangement makes both the two support blocks 42 smaller in volume, saves a cost and can support supported objects 100 with different sizes by adjusting a distance between the two support blocks 42.

Further, the support block 42 is provided with an inclined plane at an end of the support block 42 away from the slide rail 41. The inclined plane is configured to abut against the supported object 100. The arrangement of the inclined plane increases a contact area between the support block 42 and the supported object 100, improving the stability of support.

Optionally, the lift desk further includes a non-slip pad 422. The non-slip pad 422 is disposed on the incline plane. Optionally, the non-slip pad 422 is stuck to the incline plane. The arrangement can prevent the supported object 100 from slipping, further improving the safety of use.

Concerning the lift mechanism 5, in the present embodiment, specifically, the lift mechanism 5 includes a linkage assembly 51 and a drive member 52. The linkage assembly 51 is disposed between the support base 1 and the first desk board 2. The drive member 52 is configured to drive the linkage assembly 51 to rotate so as to adjust a distance between the first desk board 2 and the support base 1. With such an arrangement, the rotation of the linkage assembly 51 is transformed into the lifting motion of the first desk board 2, making the first desk board 2 lifted and lowered more stably.

Concerning the structure of the linkage assembly 51, in the present embodiment, specifically, the linkage assembly 51 includes two drive rods 511 and two driven rods 512. The two drive rods 511 are parallel to and spaced apart from each other. One end of the drive rod 511 is rotatably connected to the first desk board 2 and the other end of the drive rod 511 is rotatably connected to the support base 1. The two drive rods 511 are disposed on two opposite sides of the first desk board 2 and two opposite sides of the support base 1, respectively. The two drive rods 511 are connected to an output end of the drive member 52 by a synchronizing member, where the synchronizing member is fixed between the two drive rods 511. The drive member 52 may optionally be a pushrod motor or an electric cylinder. One end of the drive member 52 is hinged to the support base 1 and the other end of the drive member 52 is hinged to the synchronizing member. The two driven rods 512 are parallel to and spaced apart from each other. One end of the driven rod 512 is rotatably connected to the first desk board 2 and the other end of the driven rod 512 is rotatably connected to the support base 1. The two driven rods 512 are also disposed on the two opposite sides of the first desk board 2 and the two opposite sides of the support base 1, respectively. With such an arrangement, the first desk board 2 will not turn over or tilt when lifted or lowered.

Optionally, the support base 1 is provided with a limiting member 6. The limiting member 6 is configured to abut against the drive rod 511 when the first desk board 2 is lifted to a limit position. Further, the drive rod 511 and the driven rod 512 positioned on the same side of the support base 1 are spaced apart from each other. The limiting member 6 is provided between the drive rod 511 and the driven rod 512 so that the limiting member 6 is configured to abut against a side of the drive rod 511 facing towards the driven rod 512 when the first desk board 2 is lifted to a limit position and abut against a side of the driven rod 512 facing towards the drive rod 511 when the first desk board 2 is lowered to a limit position. With such an arrangement, the limiting member 6 at one position limits two limit positions of the first desk board 2 so that the structure is compact and the cost is saved.

In the present embodiment, optionally, the first desk board 2 and the second desk board 3 are parallel to each other. Along a direction parallel to a board surface of the first desk board 2, a part of the second desk board 3 projects out of the first desk board 2. This arrangement prevents the second desk board 3 in use from being blocked by the first desk board 2, improving the convenience of use of the second desk board 3.

When the lift desk is used, elbows of a user may be outside the lift desk and the long-term use may cause damages to arms of the user. For this reason, in the present embodiment, support board regions 32 extend from two sides of an end of the second desk board 3 projecting out of the first desk board 2 respectively. With the arrangement of the support board regions 32, it is convenient for the user to place the arms when the user uses the second desk board 3, improving the comfort of the user.

In an embodiment, optionally, an edge of the first desk board 2 is provided with an escape groove 26 extending through two opposite side board surfaces of the first desk board 2. A projection of the groove 31 in a direction perpendicular to the board surface of the first desk board 2 is located in the escape groove 26. The support block 42 is configured to cooperate with the escape groove 26 and the second desk board 3 to support the supported object 100. During use, a part of the supported object 100 is located in the escape groove 26. Such an arrangement not only saves a material and reduces the cost but also provides a space for placing the supported object 100, making the structure of the lift desk more compact.

Optionally, the first desk board 2 is provided with two connecting pieces 21. The second desk board 3 is connected to the first desk board 2 by the two connecting pieces 21. The two connecting pieces 21 are positioned at two opposite sides of the escape groove 26 respectively. Such an arrangement allows the two desk boards to be plate boards, improving production efficiency.

Further, the connecting piece 21 is provided with a carrying portion at an end of the connecting piece 21 away from the first desk board 2. A surface of the second desk board 3 facing away from the first desk board 2 abuts against the carrying portion. Such an arrangement improves the stability of the second desk board 3.

Optionally, the first desk board 2 is provided with a cylindrical first placement groove 22 for holding items. Such an arrangement improves the storage capacity of the first desk board 2.

Optionally, the first desk board 2 is further provided with an elongated second placement groove 23 for holding items. Such an arrangement further improves the storage capacity of the first desk board 2. A tablet 200 or a mobile phone 300 may be inserted into the second placement groove 23, and the tablet 200 or the mobile phone 300 in an inclined state may be supported by an edge of the second placement groove 23.

Typically, the first desk board 2 is made of wood with poor wear resistance. In order to prevent the first placement groove 22 and the second placement groove 23 from being worn, in the present embodiment, optionally, the lift desk further includes a first placement tray 24 and a second placement tray 25 both of which are made of plastics. The first placement tray 24 and the second placement tray 25 are respectively embedded in the first placement groove 22 and the second placement groove 23.
